CHDKPTP on RaspberryPi - How to install?

I just new to Linux and Raspberry Pi (B+, raspbian) and have some problems getting CHDKPTP (incl. gui) installed.

* I downloaded chdkptp-r330-raspbian-gui.zip. Right one? Or r650, r599 ...?* unzipped to /home/pi/CHDKPTP/* saved "chdkptp.sh to /bin with CHDKPTP_DIR=/home/pi/CHDKPTP* restarted* tried to run chdkptp from desktop and from terminal, nothing happened* installed all the libs mentioned in the readme-libs.txt and tried to run again - nothing
